For example, the one or more output devices may include the display device 106, other display devices, lights, and/or speakers. Additionally, depending on the particular embodiment, the kiosk 102 may be configured as a user-operated mobile device or system.

Additionally, the system 10 may include a consultation center 112 located remotely from the kiosk 102 and/or user computing device 118. The consultation center 112 may be coupled to the kiosk 102 and/or the user computing device 118, such that a user may conduct a semi-personal consultation with a consultant that is located at the consultation center 112. As an example, the user may access a user interface (such as those described below) to select a consultant, who will then be contacted utilizing the communications device 108. The consultation center 112 may include a plurality of audio, video, and/or data communication hardware and software and may receive (or initiate) the call to begin the consultation with the user. The consultant may control at least a portion of the functionality of the kiosk 102 and/or user computing device 128 to remotely to capture images, dispense the calibration device 110, and/or perform other functions.

Depending on the particular embodiment, user interfaces and/or other data may be provided by the kiosk 102, user computing device 118, and/or a native remote computing device 114. The native remote computing device 114 may include a memory component 140, which stores receiving logic 144 a, analysis logic 144 b, and/or other logic for facilitating performance of the consultation. With this logic, the native remote computing device 114 may send user interface data to the kiosk 102 and/or user computing device 118. Additionally, the native remote computing device 114 may determine whether the consultation is a personal consultation, semi-personal consultation, and/or virtual consultation. If the consultation is a semi-personal consultation, the native remote computing device 114 may interact with the consultation center 112 to facilitate the consultation. If the consultation is a virtual consultation, the native remote computing device 114 may perform the consultation analysis and/or perform other functions. More specifically, while in some embodiments, the kiosk 102 and/or user computing device 118 may include logic and/or hardware for providing user interfaces, performing the analysis, and providing treatment and product recommendations, in some embodiments, the native remote computing device 114 may provide this functionality.

Depending on whether the consultation is a personal consultation, a semi-personal consultation, and/or a virtual consultation, the native remote computing device 114 may access the consultation center 112, as described above with regard to the kiosk 102. Additionally, the native remote computing device 114 and/or the user computing device 118 may access the foreign remote computing device 116 to retrieve data from a previous consultation, share the consultation with friends and/or perform other functions.

Also included is a foreign remote computing device 116. The foreign remote computing device 116 may be configured as a computing device for storing data. As an example, the foreign remote computing device 116 may be configured as a social network server, a storage server, a user computing device, a consultation server, and/or other device for performing the described functionality. As such, the kiosk 102 and/or user computing device 118 may prompt the user to save the data from the consultation to the foreign remote computing device 116 for subsequent retrieval by other devices, such as the kiosk 102, the native remote computing device, and/or the user computing device 118. If the user is prompted to save the data on the foreign remote computing device 116, such as a social network, the kiosk 102 may have a dedicated profile page on the social network to upload the consultation data. The consultation data may be tagged for the user, so that the data is also included in the user's profile page. In order to protect privacy, the data may be redacted on any public posting of the data and/or provided so that only the user may access the data. Similarly, in some embodiments, the kiosk 102 and/or the user computing device 118 can upload the consultation data directly to the user's profile page. In such a scenario, the kiosk 102 and/or the user computing device 118 may receive the user's login information.

As an example, if the user is performing a skin treatment, an image of the user's face may be captured. After the consultation, the user may wish to store the image, so that the user can compare this image with past and/or future images. As such, the kiosk 102, the user computing device 118, the native remote computing device 114, and/or the consultation center 112 may facilitate sending and/or storing this data. Depending on the particular embodiment, the data may be sent to the native remote computing device 114, the foreign remote computing device 116, and/or a user computing device 118.

Additionally, while the native remote computing device 114 is illustrated with the receiving logic 144 a and the analysis logic 144 b as separate logical components, this is also an example. In some embodiments, a single piece of logic may cause the native remote computing device 114 to provide the described functionality.

FIG. 2B depicts one embodiment of a calibration device 110 that may be utilized for providing a color calibration of images for a consultation. The calibration device 110 may be configured as a headband formed from a flexible, elongate strip of material 259 having a first end 253 a, a second end 253 b, and one or more slits 253 c adjacent the second end 253 b for receiving the first end 253 a. In some embodiments, the strip of material 259 has a width W from about 0.5 cm to about 6 cm and a length L from about 40 cm to about 100 cm. In some embodiments, the headband has a width W from about 2 cm to about 4 cm and a length L from about 60 cm to about 80 cm. By inserting the first end 253 a into the slit 253 c, the strip of material 259 can be formed into an adjustable ring or headband that may be sized to accommodate various users.

The headband includes alignment indicator 252, at least one color correction region 256 (which may include a first color correction region 256, a second color correction region 256, etc.), an identifier 255, a measurement component 257, at least one resolution indicator 254, and/or other components. The alignment indicator 252 may generally bifurcate the headband. In one embodiment, the alignment indicator 252 is provided in the form of a substantially vertical stripe, which a user of the headband can align with the mid-point of their face during use. The alignment indicator 252 can be provided in a wide range of sizes, shapes, and colors. In some embodiments, the color correction region 256 includes a plurality of color chips 258 having at least one predetermined chip color, each chip color being a different color.

Additionally, the measurement component 257, and/or resolution indicator 254 (which may be embodied as green cross shapes on either side of the alignment indicator 252) are arranged on opposite sides of the alignment indicator 252. In some embodiments, the color correction region 256, the measurement component 257, and/or resolution indicator 254 are symmetrically arranged on opposite sides of the alignment indicator 252. The calibration device 110 may be made from a wide variety of materials, including paper, cardboard, and plastics.

Additionally, in some embodiments the calibration device 110 may be constructed of a predetermined background color that is predicted to be absent from the target substrate. Similarly, in some embodiments, the background color is selected based on a predicted contrast in the LAB color space. This color may include blue, green, and/or other colors.

During the consultation at the kiosk 102 and/or at the user computing device 118, the user may wear the calibration device 110 on his/her head with the alignment indicator 252 aligned near the mid-point of the subject's face or subject's forehead so that color correction regions 256 are positioned on either side of the face. In many instances, it may be desirable to capture an image of the face from an oblique angle thereto (such as at a 45 degree angle), as seen for example in FIG. 8. In these instances, having a color correction area positioned on either side of the mid-point of the face permits an image capture at any oblique angle on either side of the face without having to reposition the headband so that a color correction region 256, resolution indicator 254, and/or measurement component 257 are within the field of the captured image.

The image may be captured at an oblique angle to more provide visual access to the cheek and eye area of the target substrate with a reduced effect from shadows and distortion. In some embodiments, the cheek and eye areas of the face provide a suitable area for wrinkle and spot detection, the oblique angle may be utilized.

Generally speaking, the user's hair may be pulled back or otherwise arranged so that it does not cover the color correction region 256, the resolution indicator 254, and/or measurement component 257, and the user's head should be rotated from about 30 degrees to about 60 degrees relative to the image capture device at the time of taking the image (e.g., somewhere between a profile or side image and an image taken looking directly into the image capture device).

As discussed in more detail below, the components of the calibration device 110 may be utilized for the kiosk 102, user computing device 118, and/or native remote computing device 114 to adjust imagery to provide a consistent analysis of the target substrate.

As illustrated, the color correction regions 256 may include a plurality of color chips 258 in the form of squares (or other shapes) of varying colors. Additionally, the alignment indicator 252 and/or other markings on the calibration device 110 may be different colors.

While each of the plurality of color chips 258 of the color correction regions 256 are illustrated as being square in shape; this is not a requirement of the calibration device 110. Rectangular areas and/or other shapes may be utilized so as to be used in the calibration device 110 of the present disclosure. According to certain embodiments, the calibration device 110 may also include instructions disposed thereon. Depending on the particular embodiment, the instructions may be disposed on a backside of the calibration device 110. As described more fully hereafter, in use, the known colors on the headband may be compared to color values captured in an image of the headband during a consultation. The facial image can then be color corrected based upon the difference between the known color values of the color correction region 256 of the calibration device 110 and the color values of the color correction region 256 captured in an image by the image capture device 104 a, 104 b. Use of the same type of calibration device 110 with multiple different image capture devices 104 a, 104 b provides a common color calibration standard that enables a user's image to be captured by a variety of different image capture devices and then color corrected so that the corrected image most closely resembles the true colors of the user's face regardless of what type of image capture device is used. This further enables more meaningful tracking of user's experience over time with one or more cosmetic products using one or more devices.

As illustrated, the calibration device 110 may be included as part of a kit. The product package 298 may also include a cosmetic product 299, which may be specifically designed to treat a condition of a subject. However, in some embodiments, the product 299 may simply be a general treatment product that applies to all subjects. Depending on the particular embodiment, the calibration device 110 may be included inside the product package 298 and/or may be adhered to a wall of the product package 298.

As illustrated, the user interface 960 may be configured to display an image 962 of the user that has been altered from the version captured by the image capture device 104 a, 104 b. While the captured image may include the target substrate of the user (e.g., the right or left cheek and around the eye) and the calibration device 110, the image 962 may be adjusted to provide only the target substrate. Additionally, other image processing may be performed, which may include a color correction, spatial image adjustment, and facial characteristic analysis to identify wrinkles and/or other facial characteristics, which have been marked with indicators 964.

Referring again to FIG. 9, the user interface 960 may also include a “perform spot analysis” option 966, a “view image” option 968, a “view past results” option 974, a “chat with a consultant” option 976, and a “connect with social media” option 978.

Additionally, the recommended product 980 may be sold and/or provided with the calibration device 110 in the form of a kit.

It should also be understood that in some embodiments, the user may desire a change to his/her appearance and/or health. In such embodiments, a user interface may be provided to the user for indicating the change that the user wishes to make As an example, if the subject wishes to change his/her hair color, the user may indicate this change in one of the user interfaces. In response, the kiosk 102, user computing device 118, consultation center 112, native remote computing device 114, and/or foreign remote computing device 116 can provide the user with a pallet of images of the subject with the different hair colors that are possible with the subject's target substrate. The user may then select the desired color and the products and/or treatment may be provided for creating the desired result.

It should also be understood that while the user interfaces depicted herein may be configured to facilitate the communication of data among the native remote computing device 114, the consultation center 112, the kiosk 102, the foreign remote computing device 116, and/or the user computing device 118. More specifically, in some embodiments, the user computing device 118 may receive user input, which is sent to the native remote computing device 118. The native remote computing device 118 may send the data to the consultation center 112 for viewing by the consultant. The consultant may then discuss the results with the user.

FIG. 10 depicts a user interface 1060 for identifying spots on the target substrate, according to some embodiments disclosed herein. As illustrated, once the image of the user has been altered for consistency, an analysis may be performed to determine at least one facial characteristic and other issues in the target substrate. More specifically, in FIG. 10, the image 1062 (a non-limiting example of an altered image) may indicate the areas of spots with indicators 1064 on the user's face.

Also included in the user interface 1060 are a “perform wrinkle analysis” option 1066, a “view image” option 1068, a “view past results” option 1070, an analysis scale 1072, a “print results” option 1074, a “chat with a consultant” option 1076, and a “connect with social media” option 1078. The perform wrinkle analysis option 1066 may be configured to send the user back to the user interface 960.

The view past results option 1070 may provide the user with analysis and/or other data from previous consultations. The print results option 1074 may send at least a portion of the data from the user interface 1060 to a printer. The chat with a consultant option 1076 may place the user in contact with a consultant, as discussed above. The connection with social media option 1078 may allow the user to save, post, upload, and/or perform other interactions with a social network.

Also included is a recommended product 1080, which has been determined as being beneficial based on the identified facial characteristics and the user's other information. A “purchase” option 1082 may provide the user with the ability to immediately purchase the recommended product 1080.

It should be understood that while spots are the depicted defect in FIG. 10, this is merely an example. More specifically, any type of condition may be identified, depending on the particular embodiments. Examples for skin include moles, freckles, pores, wrinkles, spots, etc. Examples for hair include split ends, gray hair, thinning hair, etc. Some methods suitable for use with the present invention for analyzing skin images are described in U.S. Pat. No. 6,571,003.

It should also be understood that, as illustrated in FIGS. 9 and 10, in some embodiments, an altered image that is based on the original uploaded image and the location of the defect areas may be provided. The altered image visually identifies the plurality of defect areas located in the uploaded image by electronically altering the color of a plurality of pixels substantially in the area containing the skin defect (e.g., on or around the defect area) to at least one color visually distinct from the skin color of the uploaded image. For example, the skin color of each pixel in the defect area may be shifted to a shade of blue to create a transparent overlay. In another example, a circle could be drawn around each of the facial characteristics to visually identify the location of the spots. Other alterations may also be provided.

Additionally, a numerical severity may be associated with the defect areas. In one embodiment, a color content associated with the defect area may be subtracted from the color content of the area immediately surrounding the defect area. For example, if the pixels used to create a red spot have a red content of 60% and the pixels used to create the surrounding skin color have a red content of 10%, then the numerical severity associated with the red spot defect in this example may be determined to be 50. Similarly, in some embodiments, the number of geometric coordinates necessary to cover the defect area is the numerical severity. For example, if a detected pore covers 30 pixels, then the numerical severity associated with that pore may be determined to be 30. The severity of multiple instances of a particular defect type may be aggregated. For example, multiple severities may be summed or averaged.

Further, the aggregated severity may be normalized, based on human perception coefficients. For example, if it is determined in a clinical study that red spots are twice as noticeable as brown spots, the aggregated severity associated with the red spot analysis may be doubled. Alternatively, in this example, the aggregated brown spot severity may be halved. Of course, a person of skill in the art will readily appreciate that more than two defect types may be normalized.

A percentile for the normalized severity may additionally be determined using data associated with a certain population of people. The population data used may be specific to the analyzed person's age, geographic location, ethnic origin, or any other factor. For example, if 55% of a sample group of people in the analyzed person's age group had a normalized severity for the current defect type below the analyzed person's severity, and 45% of the sample group had a severity above the analyzed person's severity, then a percentile of 55 or 56 is determined.

When there are no more defect types to process, an overall skin severity and an overall percentile may be calculated. The overall skin severity may be an aggregation of the plurality of individual skin defect severities. For example, the severities determined by each defect may be summed or averaged. The overall percentile may be calculated as described above for the individual skin defect percentiles; however, a different data set representing overall severities of a population of people may be used. Again, the population data may be selected based on the analyzed person's demographics.

In addition to an overall skin severity based on the aggregation of individual skin defect severities, one or more overall skin characteristics may be determined. An overall skin characteristic may not depend on the detection of any individual skin defects. For example, an overall smoothness/roughness magnitude may be determined. Such a determination may include certain skin defects (e.g., analyze entire image or sub-image) or it may exclude certain skin defects (e.g., do not analyze pixels in the hyper-pigmentation defect areas).

It should also be understood that while the examples depicted in FIGS. 9 and 10 illustrate analysis of the image as a whole, in some embodiments sub-images may be determined. A sub-image is a portion of the originally acquired image upon which analysis will be performed. By eliminating a portion of the acquired image from the analysis process, fewer errors occur. For example, by excluding consideration of the eyes and nose from the analysis process, an incorrect determination that a large discoloration of the skin is present is avoided.

As an example, a decision may be made to use automatic or manual sub-image determination. In one embodiment, this decision is made by the user. However, in some embodiments the selection may be automatically determined In such an instance, the native remote computing device 114 (and/or other computing device) may analyze or partially analyze the image automatically, and based on the results of that analysis, a decision is made regarding whether to use automatic or manual sub-image determination. For example, if the automatic sub-image determination includes a result indicative of a confidence level (e.g., how sure is that a nose has been found), and that confidence result is below some predetermined threshold, then a manual sub-image determination may be performed.

If a manual sub-image determination is selected, a decision may be made to use prompted or unprompted sub-image determination. This decision may be made by the user. If unprompted sub-image determination is selected, the operator draws a virtual border for the sub-image. If prompted sub-image determination is selected, the native remote computing device 114 and/or other computing device prompts the user to select a series of landmarks on the displayed image (e.g., corner of the mouth, then corner of the nose, then corner of the eye, etc.). Subsequently, the native remote computing device 114 and/or other computing device may draw in the sub-image border by connecting the landmarks.

If automatic sub-image determination is selected, a decision is made to use fully automatic or semi-automatic sub-image determination. If semi-automatic sub-image determination is selected, the user may select several landmarks, but not all of the landmarks, for the sub-image. The native remote computing device 114 then may determine the remaining landmarks automatically by comparing the user entered landmarks to a predetermined landmark template (e.g., a standard mask) and interpolating the user entered landmarks using shape warping algorithms.

Similarly, as an example, the remaining landmarks may be calculated by taking the spatial difference vector (delta x, delta y) between the user entered landmarks and a standard mask for each of the user entered landmarks. Then, the remaining landmarks may be calculated using a bilinear interpolation of the spatial difference vectors and the x, y coordinates of the two closet user entered landmarks. Subsequently, the native remote computing device 114 may draw in the sub-image border by connecting the landmarks (both user entered landmarks and automatically determined landmarks).

If fully automatic sub-image determination is selected, the native remote computing device 114 and/or other computing device determines all of the landmarks for the sub-image automatically by searching for patterns in the digital image indicative of predetermined landmarks. Once the main sub-image is determined, additional sub-images may be determined. In one embodiment, an arc is drawn by the native remote computing device 114 between two of the landmarks to define an “under eye” sub-image border. The user may then adjust the size of the “under eye” sub-image. In some embodiments, a sub-image is electronically determined by comparing a plurality of color values of a plurality of pixels to a predetermined threshold indicative of skin color.

Once the sub-images are determined, the sub-images may be analyzed to locate defect areas and compare the severity of the defect areas to an average skin severity of a population of people. In one embodiment, defect areas are areas in the sub-image which meet certain criteria (e.g., a red spot). The severity of a particular instance of a defect is an estimation of the degree to which humans perceive one defect as being “worse” than another. For example, a large red spot is considered more severe than a small red spot. Many different defect types may be located. For example, skin elasticity features such as wrinkles and/or fine lines may be located. Skin smoothness, skin texture, follicular pores, inflamed red spots such as acne, hyperpigmented spots such as senile lentigenes, nevi, freckles, as well as many other skin defects may also be located using a variety of known algorithms.

Additionally, an index variable may be initialized to zero. The index variable may be utilized to keep track of which type of skin defect is being analyzed. If only one defect type is being analyzed, the index variable may be eliminated. A plurality of areas in the sub-image may contain the current defect type are located. For example, if the sub-image contains six red spots (as defined by a known red spot detection algorithm) then six locations in the sub-image are determined. Each location may be identified using a single set of geometric coordinates specifying the approximate center of the located defect, or, each location may be identified by a set of geographic coordinates covering a region affected by the current defect type.

FIG. 11 depicts a user interface 1160 for providing a communication portal with a consultant, according to some embodiments disclosed herein. More specifically, in response to selection of the chat with an consultant options 976, 1076 in FIGS. 9 and 10, respectively, the user interface 1160 may be provided. From the user interface 1160, the user may conduct a video conference to discuss one or more aspects of the consultation.

It should be understood that while in some embodiments, the user interface 1160 is provided in response to selection of the chat with a consultant options 976, 1076, this is merely an example. More specifically, if the consultation is a personal consultation, selection of these options may call the consultant to physically walk over to the user to provide the assistance.

FIG. 12 depicts a user interface 1260 for providing treatment and/or product recommendations to a user, according to some embodiments disclosed herein. As illustrated, once the image analysis is complete on the user image, the service can review the information, provide product recommendations, provide treatment recommendations, and/or provide other services. More specifically, the recommended products may be provided in the user interface 1260, with purchase options 1262 a, 1262 b, and 1262 c. Additionally provided in the user interface 1260 is a treatment recommendation for the subject.

Additionally, a simulated image showing an improvement and/or worsening to the defect areas may be provided. Simulating worsening may be useful when the consultant is recommending a treatment using a product which prevents skin degradation to show the user the potential affects if he/she fails to take precautionary measures. Simulating improvements may be useful when the consultant is recommending a treatment using a product that eliminates and/or hides skin defects to show the analyzed person the potential benefits of the products.

Similarly, in some embodiments, a text chat and/or other communications may be provided for allowing the user to interact with the consultant. In some embodiments, a video recording option may be provided to allow the user to save the consultation for later use.

Example Back-End Processing Windows

FIGS. 13A-13D depict a plurality of images that illustrates color correction, according to some embodiments disclosed herein. Referring initially to window 1342 in FIG. 13A, image processing may begin with receiving an uploaded image and converting the image from RGB format to LAB format. In window 1344 and 1346, the B channel of the LAB converted image may then be filtered. By filtering the B channel between a threshold (e.g., 65-110), the blue coloring of the calibration device 110 may be shown as white (binary 1) and the non-blue portions of the image may be shown as black (binary 0). From this data, in FIG. 1348, the calibration device 110 in the RGB image may be located. Additionally, because the calibration device 110 may include the alignment indicator 252, two separate portions of the calibration device 110 may be identified. Because of this, a measurement of the respective lengths of the portions may be performed. The portion of the greatest length is the portion of the calibration device of interest.

In the window 1350, the resolution indicator 254 may then be identified. The resolution indicator 254 may be identified by finding pixels in the LAB converted image that potentially could be the resolution indicator. From this another filtering may be performed to filter out the resolution indicator 254. Additionally in window 1350, a central point of the resolution indicator 254 may be identified by determining the coordinates of the pixels in the resolution indicator and determining the mean coordinate point. Additionally, to determine which arm of the resolution vector is the substantially vertical arm and which is the substantially horizontal arm, in window 1352 Eigen-Vectors may be determined from the central point to each pixel in the resolution indicator 254. As the horizontal arm is longer, the direction with the largest Eigen-Vector may be identified as the horizontal arm. In window a boundary for separation of the resolution device 254 may be determined In window 1356, the resolution indicator 254 may be highlighted in the RGB image.

Referring now to window 1358 in FIG. 13B, the RGB image may be retrieved and the previously determined horizontal arm may be separated from the vertical arm of the resolution indicator 254. In window 1362 a bounding box may then be constructed around the horizontal arm of the resolution indicator 254. The distance (in pixels) of the diagonal of the bounding box may then be divided by the known actual length resolution indicator 254 to determine the resolution of the image, as illustrated in window 1366.

Once the resolution indicator has been determined, as discussed above, the calibration device 110 may be identified uniquely. More specifically, as there may be other objects in the uploaded image that are the same (or similar) color as the calibration device 110, windows 1368-1374 illustrate actions that may be used to remove those extraneous objects. Referring now to window 1368 in FIG. 13C, a line that is perpendicular to the vertical arm of the resolution indicator 254 may be determined. From this line, a box may be created that spans a predetermined length in opposing directions from the perpendicular line. As an example, if the known width of the calibration device 110 is 3 inches, the box may be created 1.5 inches on either side of the perpendicular line. Similarly, the box may span a length that begins from the vertical line and extends ½ the known length of the calibration device in opposing directions. From this box, the calibration device may be identified as being within the boundaries of the box, as shown in window 1374. In window 1374, the RGB image may then be applied to uniquely identify the calibration device 110.

As noted above, the calibration device 110 may include a plurality of color chips. The plurality of color chips may be mapped from the image to determine which values to retrieve from the database for comparison. Based on the observed values and the expected values, a color correction may be determined Referring now to window 1376 in FIG. 13D, a template of a color chip may be created. In window 1378, an angle of the calibration device 254 in the uploaded image may be determined from the previously determined vertical arm. In window 1380, the template may be rotated the determined angle. In window 1382, the template may be applied to the uploaded image to determine possible color chips in the uploaded image. In window 1384, concentric circles may be created to determine approximate locations of the actual color chips from the resolution indicator 254. In window 1386, a determination of the color chips may be identified. In window 1388 the color chips may be numbered. In window 1390, based on the numbered color chips and the known color of each of the color chips, the image may be color corrected.

FIG. 14 depicts a plurality of images 1480 that illustrates final results from color correction. As illustrated, each of the images may be altered according to the process described herein to provide an adjusted image with standard image characteristics. More specifically, the images 1482 were captured by a plurality of different image capture devices 104 a, 104 b. As an example, image 1482 a was captured with the Canon Powershot A510; the image 1482 b was captured with the Canon Powershot S2 IS; the image 1482 c was captured with the Canon Powershot S3 IS; the image 1482 d was captured with the Canon Powershot S70; the image 1482 e was captured with the Canon Powershot SD550; the image 1482 f was captured with the KODAK EASYSHARE C743; the image 1482 g was captured with the KODAK CX6445; the image 1482 h was captured with the KODAK DX7590; and the image 1482 i was captured with the KODAK V705. As the images 1482 were taken with different cameras, each of the images 1482 may have different color characteristics. However, through the color correction process described above, the images 1484 are consistent. Additionally, once the color correction has been performed, other alterations to the images may be made, as described below.

As an example, the uploaded digital image may be compared to a mannequin image to provide feature detection and spatial image adjustment. As such, the mannequin image may be utilized to determine relative head position, relative head tilt, relative head pitch, and/or relative head yaw. The uploaded image may then be altered to substantially match the mannequin image according to at least one image characteristic, such as size, orientation, position, etc., as described below with regard to FIGS. 15A and 15B.

FIGS. 15A and 15B depict a plurality of images that illustrates feature detection and spatial image adjustment, according to some embodiments disclosed herein. As illustrated, the color corrected image in window 1580 may be accessed for detecting at least one feature of the image. From the color corrected image, a two-tone facial mask image in window 1582 may be created to determine various features on the target substrate. The features may include a corner of the nostril, a corner of the eye, a corner of the mouth, and/or other features on the subject. In window 1584, a first feature (e.g., the corner of the nostril) may be determined. This feature may be compared with a mannequin image (not illustrated) that has a corresponding first feature with a known location.

Based on the known location of the first feature on the mannequin image, a search for a second feature on the uploaded image may be determined (e.g., a corner of the eye). The second feature may be located at within a constrained search area, which may be within a predetermined distance from the first feature, as determined from the mannequin image. If the second feature does not match the second feature on the mannequin image, the uploaded image (and/or the corresponding coordinate system) may be altered (e.g., rotated, cropped, etc.) to allow the features to align. Similarly, in the window 1588, a third feature (e.g., a corner of the mouth) may be determined as also being a predetermined distance from the first feature and/or the second feature, based on a corresponding third feature of the mannequin image. In the window 1590, the image may be cropped and/or rotated to match the characteristics of the mannequin image. The altered image may then be provided in window 1592.

It will be understood that by comparing the uploaded image to a mannequin image, the landmarks and features of the uploaded image may be normalized More specifically, because many uploaded images are compared with a standard mannequin image, the alterations to the uploaded images will be consistent, thus providing a standard result by which to perform spot and wrinkle analysis.

FIG. 15B depicts a plurality of color corrected images 1594, as described above. Also included is a plurality of rotated images 1596, which have been compared with a mannequin image and rotated, based on the determined features. A plurality of cropped images 1598 is also included, which provides the resulting image for spot and/or wrinkle analysis, as described herein.

Example Back-End Processes

FIG. 21 depicts a flowchart for altering an image for analysis, according to some embodiments disclosed herein. Similar to the discussion from FIG. 14 above, in block 2130, an image of the subject may be received. As discussed above, the image may be received from an image capture device 104 a, 104 b, from a foreign remote computing device 116 (such as a social network), from the user computing device 118, and/or from another source. In block 2132, a color correction of the image may be performed. In block 2134 a spatial image adjustment may be performed.

More specifically, as described above, the uploaded digital image may be compared to a mannequin image. The mannequin image may have a predetermined relative head position, relative head tilt, and/or relative head yaw. The uploaded digital image may then be compared with the mannequin image. If the uploaded digital image does not match the mannequin image, the uploaded digital image may be altered to substantially match the mannequin image according to at least one image characteristic, such as size, orientation, position, etc. In some embodiments, altering the uploaded digital image includes matching a predetermined point on the portion of the face of the subject with a corresponding point on the portion of the face of the mannequin. In block 2136, the image may be compared to a mask to further adjust the characteristics of the uploaded image. In block 2138, feature analysis may be performed.

FIG. 22 depicts a flowchart for performing color correction, according to some embodiments disclosed herein. As illustrated, from FIG. 21, the block 2132 may include a plurality of actions. More specifically, in block 2230 a calibration device detection may be performed. In block 2232, the resolution indicator 254 may be detected. In block 2234 the resolution indicator may be separated into a horizontal arm and a vertical arm. In block 2236, image resolution may be estimated from the resolution indicator. More specifically, the horizontal arm of the resolution indicator 254 may have a predetermined length. Based on the number of pixels that the resolution indicator 254 spans in the image the resolution of the image may be determined.

Additionally, determinations may be made regarding whether the uploaded image meets resolution thresholds. More specifically, in some embodiments the image should be at least about 220 pixels per inch (and in some embodiments between about 150 to about 500 pixels per inch), which would be a predetermined first resolution threshold. This threshold has been determined as being adequate for performing wrinkle and/or spot analysis. If the uploaded image meets that requirement, the image may be processed as described herein. If not, a determination may be made regarding whether the uploaded image is of a predetermined second resolution threshold that is available for up-conversion. If not, the image may be rejected. If so, the image may be up-converted to meet the 220 per inch threshold.

Returning to FIG. 22, in block 2238 the calibration device 110 may be isolated uniquely. As discussed above, while detecting the calibration device 110 in block 2230 may locate the calibration device, other objects in the image may have the same color as the calibration device 110 and may be mistakenly identified as well. As such, block 2238 utilizes the determined resolution indicator 254 to remove any extraneous objects that may be identified as the calibration device 110. In block 2240, a phase 1 color correction may be performed. In block 2242, a phase 2 color correction may be performed. In block 2244, a phase 3 color correction may be performed.

FIG. 23 depicts a flowchart for detecting a calibration device, according to some embodiments disclosed herein. As illustrated in the block 2230 of FIG. 22, calibration device 110 was detected. The blocks of FIG. 23 further elaborate on the device detection of FIG. 22. More specifically, in block 2330, the uploaded image may be converted from RGB format to LAB format. In block 2332, pixels in the B channel that are within a minimum and maximum threshold may be found. In block 2334, false positive pixels may be filtered by computing the major axis length and eccentricity of an equivalent ellipse.

FIG. 24 depicts a flowchart for detecting a resolution indicator, according to some embodiments disclosed herein. More specifically, in block 2232 from FIG. 22, a plurality of actions may be performed. More specifically, in block 2430, the LAB image may be retrieved (e.g. from memory). In block 2432, the calibration device (RGB) image from block 2334 may be retrieved. In block 2434, each of these images may be analyzed to find pixels that satisfy the threshold constraints of both of the RGB image and the LAB image, as well as being located within a predetermined area for the calibration device 110. As discussed above, the LAB image determines thresholds for potential calibration devices. The calibration device image from 2334 may be used to filter out portions that are not in the appropriate area for the calibration device 110.

FIG. 25 depicts a flowchart for separating a resolution indicator, according to some embodiments disclosed herein. More specifically, from FIG. 22, the block 2234 may be expanded into a plurality of actions. As illustrated in block 2530, a central point of the resolution indicator may be found. As discussed above, the central point may be found by determining the coordinates of the pixels in the resolution indicator 254. These coordinates may then be averaged, which yields the central point.

In block 2532, an Eigen-analysis of points in the resolution indicator space may be performed. More specifically, to determine which arm of the resolution indicator 254 is the horizontal arm, the Eigen-Vectors may be determined from the central point to each pixel in the resolution indicator 254. The Eigen-Vectors are then utilized to determine which a direction of maximum radiation. From this determination, the horizontal arm (which in this example is longer) may be determined. In block 2534, an orientation of the points with respect to the largest Eigen-Vector may be found. In block 2536, points that have an orientation that lies between a predetermined boundary of the calibration device 110 may be found.

FIG. 26 depicts a flowchart for performing image resolution estimation, according to some embodiments disclosed herein. More specifically, block 2236 from FIG. 22 may include a plurality of actions. As illustrated in block 2630, an image that includes the resolution indicator 254 may be received (e.g., the image from block 2536). In block 2632, a bounding box of the resolution indicator 254 may be determined. In block 2634, a length of the diagonal of the bounding box may be computed by counting pixels of the diagonal. In block 2636, an estimated image resolution may be determined by dividing the length of the diagonal by a predetermined length value, (e.g., 1 inch).

FIG. 27 depicts a flowchart for isolating the calibration device uniquely, according to some embodiments disclosed herein. More specifically, from block 2238 in FIG. 22, a plurality of actions may be performed. As illustrated in block 2730, the resolution indicator 254 may be identified. Similarly, in block 2732, the estimated image resolution may be identified (from FIG. 26). In block 2734, a first line that has a common orientation with the vertical arm of the resolution indicator may be computed. In block 2736, a second line that is perpendicular to the vertical arm may be computed. In block 2738, the first line may be moved a second predetermined distance in the +/− direction along the perpendicular line.

More specifically, if the calibration device 110 has a known length of 7 inches, the predetermined distance may be 3.5 inches in each direction. In block 2740, the second line may be moved a second predetermined distance in the +/− direction at two locations that are parallel with the vertical arm. So, if the calibration device 110 has a known width of 3 inches, the predetermined distance would be 1.5 inches in either direction. These predetermined distances should provide a bounding box that approximately outlines the calibration device 110. In block 2742, the bounding box may be created using estimated locations. In block 2744 the calibration device image may be received. In block 2746, an intersection area between the bounding box and the calibration device may be found.

FIG. 28 depicts a flowchart for performing phase 1 image color correction, according to some embodiments disclosed herein. More specifically, from block 2240 in FIG. 22, the phase 1 image color correction may include a plurality of actions. As illustrated in block 2830, a template for a calibration device 110 may be created. The template may identify the location and color of various portions of the calibration device 110. In block 2832, the vertical arm of the resolution indicator 254 may be received. In block 2834, the vertical arm may be utilized to rotate the template (which is image specific rotation). In block 2836, the calibration device image from block 2330 may be received. In block 283, the calibration device location may be utilized to search for candidate color chips by matching the calibration device image with the template.

In block 2934, the color chips may be sorted in each quadrant in a predetermined direction. In block 2936, the inter-point distances between the color chips may be computed. More specifically, in the first concentric circle, the color chips closest to the resolution indicator 254 may be identified. In the second concentric circle, the color chips outside the closest color chips may be determined. Additionally, inter-point distances may be determined between each of the first tier color chips and each of the second tier color chips. In block 2938, the missing chip locations may be predicted utilizing known and determined special information. In block 2940, the color chips may be reordered for calibration device state estimation.

FIG. 30 depicts a flowchart for performing phase 3 image color correction, according to some embodiments disclosed herein. More specifically, from block 2244 in FIG. 22, the phase 3 image color correction may include a plurality of different actions.

FIG. 31 depicts a flowchart for performing phase 4 image color correction, according to some embodiments disclosed herein. More specifically, within block 2246 in FIG. 22, a plurality of actions may be performed. In block 3130, the expected color chip values may be received from FIG. 30. In block 3132, the expected color chip values may be converted from RGB format to LAB format. In block 3134, the L channel may be used to compute the intensity scale factor of the expected color chips.

Similarly, in block 3136, the estimated color chip values may be received. In block 3138, the estimated color chip values may be converted from RGB to LAB format. In block 3140, the A and B channels may be used to compute a color transformation of the estimated color chips. In block 3142, a single LAB to LAB color transformation may be performed to create a matrix of color transformation values. In block 3144, the transformation values may be applied on the uploaded image to create a color corrected image. Once this is complete, the process may end and/or continue in block 2134 from FIG. 21.

It should be understood that while the blocks 3130-3134 and 3136-3140 are depicted as being performed in parallel, this is merely an example.
